Abstract
The paper presents a novel approach for dynamic bandwidth allocation
(DBA) in GEO satellite networks based on adaptive predictive control.
In the proposed DBA scheme each satellite gateway (SG) uses an adaptive
predictor to forecast the future input traffic flow along with a
bandwidth controller to generate a bandwidth request to the bandwidth
manager (BM) according to a receding-horizon policy, via solution
of an optimal control problem. A multi-service traffic scenario is
considered with a careful eye to guarantee differentiated quality
of service requirements. Simulation experiments demonstrate that
the predictive DBA technique proposed in this work outperforms fixed
allocation as well as existing reactive DBA methods.
